ok quick question. I'm about to start doing some major engine stuff.
I have a 97 del sol. i currently have a stock d16y7 engine with a y8 mani on when I purchased the car. I'm assuming it has y7 injectors currently.
im about to do a y8 mini me head swap. A y8 needs bigger injectors than a y7. I think 190 vs 240.
I have everything minus new injectors for the head swap and also for a turbo setup. am planning to work on my engine in two phases. Ive been researching and buying and collecting parts for about a year now.
first I will be installing.
D16y8 head
aem tru time cam gear
aem fuel rail
aem fuel pressure regulator
aem fuel filter
arp head studs
gates timing belt and water pump and tensioner
skunk2 intake manifold with a Hondata thermal gasket
skunk2 alpha radiator with slim fans
slim fans for the ac condenser
all new silicon coolant hoses
skunk2 alpha throttle body
cai until turbo
headers until turbo
race pipe - no emissions in my county.
3 point strut bar
hondata s300 v3 also have a second chipped p28 that I don't plan on using.

then I have all my turbo parts Second phase of installation.
T3 50 trim turbo
hks blow off valve
turbo smart wastegAte
pfab manifold
piping and downpipe already fitted for my sol.
intercooler
aem tru boost gauge
aem wideband
aem oil pressure
all the oil lines
new oil pan with welded in fitting
various other bits
plan on running about 7-8 psi when this is installed
i have 450dsm injectors with the resistor box but I'm going to go with different injectors that don't need the resistor box.

now my question. I want to set up my mini me swap and run for a while and make sure all is well before turboing, the y8 needs the bigger injectors. I want to buy maybe 320 injectors for my turbo. Being than I have the s300 and I can adjust the injector size on the computer do I need to buy 240cc injectors for the y8 mini me swap or can I go ahead and get the 320cc injectors that I want and run them until I turbo. Or will my current injectors which I assume are y7 190 run ok on the y8 until I turbo. Basically I don't want to have to buy 240 injectors unless I have to because I won't be using them for long.
thanks for any replies.

 

You already have 240s

 

No

 

Then use the 240cc if on the stock computer. Even 320cc have to be calibrated to work.

the only items that you can install now to prepare yourself for turbocharger use are a upgraded clutch and brakes. Everything else has to be installed pretty much all simultaneously.
